This test is appropriate only for asphalt concrete, hot-rolled asphalt, and stone mastic asphalt mixtures. Test conditions: (i) 6 specimens with a diameter of ± mm and a height of ± mm (ii) 4 temperatures 0°C, +10°C, +15°C, +20°C, and +30°C (iii) Device—universal servohydraulic testing Author: Jan Mikolaj, Frantisek Schlosser, Lubos Remek, Martin Pitoňák, Juraj Šrámek.

The third objective was to evaluate open-graded\ud mixtures and rubber modified mixtures for water sensitivity using the ECS.\ud The ECS test results indicate that performance ranking of mixtures by asphalt\ud type or aggregate type alone cannot be made for the ECS test results due to the\ud significant interaction between asphalt and aggregate.

Conditioning procedures for the indirect tensile testing were soaking only and soaking plus freezing. Test results indicated that the mineralogy of aggregate is a dominant factor in determining the susceptibility of asphalt concrete mixtures for water damage. Other factors such as conditioning procedure and source of asphalt are of less importance.

Later, a continuum model and a concomitant test methodology are used to measure healing characteristics in asphalt mixtures that are independent of the testing conditions, sensitive to the duration of the rest period during which healing occurs, and sensitive to the.

The assessment procedure is based on the indirect tensile strength test after the conditioning method, from which the concept of the Damage Rate as an indicator for classifying the durability of mixtures against moisture damage, was by: 3.

Water sensitivity test (EN ): the retained indirect tensile strength (ITS) is determined by comparing the dry and wet ITS. This test indicates the effect of water on the asphalt mixture performance. ITS was calculated using a conventional mechanic machine that registers the load that the specimens endure before break at 50 mm/min : Marta Vila-Cortavitarte, Pedro Lastra-González, Miguel Ángel Calzada-Pérez, I.

Sabouri & P. Teymourpour. Warm and cold bituminous mixtures characterization. Filler plays a significant role in mastic cohesion and adhesion between aggregate–asphalt binder in asphalt mixes. In the majority of research on investigating moisture damage based on thermodynamic concepts, little attention has been given to the role of filler.

In the present study, 20 different combinations of asphalt mixes made with 4 filler types (stone powder, hydrated lime, calcium Cited by: 2. The main objective of this work is to evaluate the properties of hot asphalt mixtures that have been manufactured with different recycled concrete aggregate (RCA) percentages (0%, 20%, 40%, 60% and 80% of the fraction 5–13 mm) and asphalt (4%, % and 5%).

Dense asphalt mixtures were made; partially replacing the natural aggregate (NA) fraction between 5 and 13 mm. Marshall specimens Author: Debora Acosta Álvarez, Anadelys Alonso Aenlle, Antonio José Tenza-Abril, Salvador Ivorra. Moisture in asphalt concrete (AC) pavements does not only cause distresses like potholes, ravelling, etc.

but also exacerbates distresses like fatigue and rutting. Moisture susceptibility of AC mixtures is usually characterized using the Modified Lottman Test (AASHTO T) adopted in Superpave mix : Mohit Chauhan, Atul Narayan. Warm mix asphalt (WMA) has been widely accepted as a future asphalt paving technology.

Besides clear advantages, there are still some concerns regarding durability and long-term performance of pavements made with this type of asphalt mixtures.

One of the most important issues is low temperature behaviour of WMA because certain additives used for temperature reduction can affect bitumen : Marcin Stienss, Cezary Szydlowski. The asphalt content of these mixtures was determined by the “pat-paper test” (asphalt stain on paper), as shown in Figure 1.

In doing the pat-paper test, Richardson warns that the mixture must be sufficiently hot for the asphalt to be fluid.

Performance Development of. The protocol steps include selection of materials, compaction, curing, density measurements, volumetric analysis, simple performance test, and evaluation of moisture sensitivity. Mixtures utilizing two aggregate sources with different absorptions are used to show examples of applying the volumetric mix design protocol.

Moisture Sensitivity Test Protocol The procedure of moisture sensitivity testing using the Link Bitutest testing protocol [] for asphalt mixtures was followed in this investigation, where the ratio of conditioned to imaged indirect stiffness modulus is used to predict the moisture sensitivity of a particular asphalt mixture.
